For less than $1, Kate’s Style List app will give you all the deets on who Catherine is wearing, where she got it and where you can get it too.

Creator and former actress, Helen Barclay, explains where she gets the outfit info:

"She mixes high street with designer so you can find a lot of the things she wears in shops such as Reiss and Zara. I spend a lot of my time trawling fashion websites and looking at the designers' shows online so that I can identify her pieces. I also follow a lot of fashion writers on Twitter so I know what Kate will be wearing when she next appears."

The Kate’s Style List bandwagon is already very popular in the US so hop aboard!
